Proven fibre-rope handling technology, enabling operators to use
the full lifting potential of their cranes, regardless of water depth
Full capacity to max depth
MacGregor has overcome the limitations of handling heavy loads at depths using traditional steel wire-ropes byintroducing a fibre-rope crane, FibreTrac. The greatest advantage of fibre rope when handling loads in ultra-deepwater
is that it weighs virtually nothing in water. This neutral buoyancy means that, regardless of the length of rope paidout, the fibre rope does not add anything to the load experienced by the crane. Cranes can therefore retain their full
lifting capacity all the way down to maximum depth. This is in complete contrast to using wire rope, where the everincreasing weight of wire paid out limits the load permissible in relation to depth.

Gentle rope handling with integrated management system
Gentle rope handling, and a controlled environment, safeguard the condition of the fibre rope, guaranteeing a long
lifetime.
MacGregor fibre-rope cranes use a novel capstan, developed by Parkburn, as a traction winch. The Parkburn capstan
consists of two interlocking drums that gently de-tension the rope. The drums are slightly angled and offset in relation
to each other, which creates a natural and stable helix without generating any fleeting forces so the rope does not
twist on the drum. Its open design also assists with rope cooling.

•• Load capacity not limited by depth•• Low number of high-tension bends•• Large capstan contact area ensures gentle rope
handling•• Capstan design minimises heat build-up and rope
fatigue•• Design allows for twin ropes and on-board splicing•• Gentle rope spooling with regulated low-tension on
storage drum•• Integrated rope management system with 3D monitoring•• Proven MacGregor and Parkburn technologies•• Retrofit option available for existing cranes orfoundations•• Highly-efficient electric or hydraulic drives

Fibre-rope retrofit solution
MacGregor has developed a modular fibre-rope retrofit solution based on the same technology. This allows customers
to convert their existing wire-rope cranes, unlocking their full lifting potential with our exciting fibre-rope technology.

AHC subsea cranes
MacGregor’s range of active heave-compensated (AHC) subsea cranes aredesigned for accurate lifts in all conditions, including extremely cold
environments with temperatures down to -40oC. They can be delivered
with hydraulic or electric winch drives and the hydraulic power unit (HPU)
and winch can be located either on the crane or below deck.
All motions including active heave-compensation, tension-modes andauxiliary and tugger winch functions are integrated within a powerful andintuitive in-house designed control system. This assures precision andsafety during critical operations.
The cranes range in safe working load capacity up to 600 tonnes (singleline) and can work at depths beyond 4,000m. Fibre-rope solutions enable
operations at extreme depths.
All MacGregor knuckle-jib cranes are specially-designed to provide extra
high lift heights for very tall loads. This feature offers operators greater
flexibility during lift planning operations. MacGregor subsea cranes can bedelivered with a range of options including a motion-compensated ship-toship load transfer system and personnel lift.

Ship-to-ship motion-compensation system•• Safe transfer of loads between vessels•• Widened operational envelope•• Time-savings for complete lift operations•• Precise and accurate motion-compensation•• Maximum use of load capacity
For offshore vessels, the ship-to-ship motion-compensation system offers enormous safety and commercial
advantages, providing a real-world increase in weather
windows for ship-to-ship load transfers.
When operating in this mode, the crane compensatesfor rela­tive vertical movement between the crane vessel
and secondary vessel regardless of where the craneor load is positioned. A motion reference unit placedon the secondary vessel transmits movement data to
the crane’s control system via a high-speed redundant
wireless radio link.

Shipboard cranes
MacGregor and Triplex shipboard cranes aredesigned for safe, accurate deck lifts onboard
ships and offshore installations, as well as
cargo handling within harbours.
These cranes are designed to accommodate
the customer’s operational requirements andrelevant industry regulations. Numerous design
parameters are available from a full range ofsafe working loads and lifting radii to slewbearing dimension and pedestal height.

The system calculates the necessary winch compensation to minimise hook movement in relation to the loador landing zone on the secondary vessel.
It features precise tension and position control for stable
hook-on, hook-off, pickup and landing activities.
Ship-to-ship motion-compensation improves safety for
deck crew working directly with the hook and load, tasks
which are traditionally very hazardous. Pick-up and landingof the load is also much smoother and faster and can be
precisely-controlled for a wide range of loads.

3-Axis motion compensated cranes
MacGregor’s 3-axis motion compensation technology for cranes was recognised with a prestigious industry innovation
award in 2014. Telescoping or knuckle-jib cranes with this motion compensation technology are designed for
extremely accurate load positioning during offshore wind turbine, rig supply and maintenance operations.
MacGregor multi-dimensional compensation technology compensates for a vessel’s movements in the horizontal axes
(pitch and roll) as well as along the vertical axis. Standard AHC technology uses the crane’s winch to compensate forall vertical movements. The recently-developed horizontal compensation technology adds to this, ensuring that thecrane can securely keep a suspended load in a fixed position regardless of sea conditions.
The crane may also be used for non-compensated general lifting operations and ship-to-ship operations, and can becertified for personnel lifts with a specially-designed basket.

3D Motion compensator
The 3D Motion Compensator (3DMC) is a flexible retrofit device designed
to enhance the load-handling precision of an offshore crane, enabling very
accurate load positioning.
It is ideal for landing loads on small fixed platforms and can be fitted to theknuckle jib of a broad spectrum of MacGregor subsea/offshore cranes. The
3DMC compensates for the roll, pitch and heave motions of the vessel tominimise any movement of the load in relation to a fixed point in space.
The operator can opt to use the 3DMC during operations that require agreater degree of precision than that available from the standard crane,such as transferring equipment to or from offshore wind turbine structures
or any fixed platform. When not required, the 3DMC simply remains fixed tothe side of the crane’s knuckle jib allowing normal lifting operations.

Winterisation
MacGregor offshore cranes deliver excellent performance even in the toughest environmental conditions. For operating
in extremely cold climates, we have developed innovations such as:
such as:•• Fully insulated and heated, lightweight housing that protects sensitive components•• Heat-tracing for components located in exposed areas•• Specially-designed heated operator cabin with extra insulation•• Heated gangways, stairs, ladders and railings•• Special hydraulic oil and grease adapted for cold climates•• Heavy duty components designed to withstand ice removal•• Designs that prevent excessive ice build-up
These features ensure safe and reliable cold climate operation in temperatures down to -40oC and are designed inaccordance with DNV GL, BV, LRS, RMRS, ABS and other relevant class societies’ regulations.

A-frames
A-frames are designed to perform a broad range of operations, such as offshore load handling (plough deployment),
subsea load handling (anchor handling) and the launch and recovery of special tools and equipment. MacGregor
A-frames are designed for heavy subsea operations in corrosive offshore environments. A-frame lifting capacities
range from 1 to 350 tonnes. They can be delivered as self-contained, self-erecting units for mounting at the stern oreither side of a vessel.

Motioncompensatedgangways

Motion-compensated gangways
Motion-compensated gangways are designed for the safe, efficient transfer of personnel and cargo to fixed offshore
installations. Standard gangways compensate motions, however the system can be upgraded to include active-heavecompensation on the gangway’s pedestal for extreme motions. These gangways are based on our award-winning
three-axis motion crane technology. Compensation systems include active, passive or combined control methods andthe gangway can be delivered with or without an operator cabin, with pedestal height adjustment and an elevator.
The system has a small footprint. Its unique design allows personnel to access the gangway during all compensation
movements and in all positions. Multiple redundant, real-time sensors work together with the control system toguarantee safety. This sophisticated system makes operation simple and clear, giving the operator deviation feedback
with warnings that prompt the appropriate action.

C-How

Overhead-mounted overside LARS
These utilise an extremely precise, electricallydriven, heave-compensated umbilical winch for thesafe launch-and-recovery of various types of ROVs.
An extendible, telescoping snubber reduces
pendulum motions and allows locking and rotationof the load. The compact telescoping design andoverhead placement of the LARS ensures safety
and offers considerable free work space in the ROV
hangar. Crew safety and comfort can be further
enhanced by placing the side-hangar door tops
below the LARS. This allows the hangar doors to
be closed even when the ROV is deployed.

Vessel: Fugro Symphony
